Using h_errno, errno etc Cygwin DLL globals [Re: Making wget]

[Fifer, Eric]

Since we're on the topic of netdb.h and h_errno, has anyone
noticed that in the recent snapshots the symbol that appears
in libcygwin.a doesn't agree with the definition in netdb.h:

  nm libcygwin.a | grep h_errno

    00000000 ? __imp__h_errno
  
  netdb.h

    extern int * __imp_h_errno;
    #define h_errno (*__imp_h_errno)
                 
I think it should be (s/_h/__h/):

    extern int * __imp__h_errno;
    #define h_errno (*__imp__h_errno)

or reworked as:

    extern int __declspec(dllimport) h_errno;
